Description
Technical field
The utility model relates to the automobile-used how fast drive system of a kind of children electric.
Background technology
At present, existing children's electric motor vehicle all only has constant moving velocity on the market, can not select to be as required applicable to the optimum speed of oneself, such as the children that have like running at high speed when children drive, some children like low speed driving, and the children that also have like driving at moderate speed.Therefore, the automobile-used drive system of existing children electric, owing to not having how fast function, is difficult to meet various children's needs.
Summary of the invention
For the deficiencies in the prior art, the how fast drive system that provides a kind of children electric automobile-used is provided the purpose of this utility model, and it can provide multiple speed to select, and has how fast function, can meet various children's needs.
For achieving the above object, the utility model adopts following technical scheme:
The how fast drive system that children electric is automobile-used, comprise forward-reverse switch, foot-operated switch with the electrical connection of forward-reverse switch, MCU with foot-operated switch electrical connection, with metal-oxide-semiconductor, the positive and negative rotating controller of MCU electrical connection, there is the gear shifting device of multiple speed stage, with the motor of metal-oxide-semiconductor, positive and negative rotating controller electrical connection; Described MCU sends the pulse-width control signal with the dutycycle corresponding with speed stage to metal-oxide-semiconductor according to the selected speed stage of gear shifting device, described metal-oxide-semiconductor is according to the rotating speed of the duty cycle adjustment motor of pulse-width control signal.
The automobile-used how fast drive system of a kind of children electric that the utility model is set forth, its beneficial effect is: compared with prior art, the utility model is controlled the dutycycle of the pulse-width control signal that MCU sends by having the gear shifting device of multiple speed stage, by Duty ratio control metal-oxide-semiconductor, the corresponding dutycycle difference of different speed stages, thus realize the adjusting to motor rotary speed, can provide multiple speed to select, there is how fast function, can meet various children's needs.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
Please refer to shown in Fig. 1, it has demonstrated the concrete structure of the utility model preferred embodiment, the how fast drive system that children electric is automobile-used, comprise forward-reverse switch 10, the foot-operated switch 20 being electrically connected with forward-reverse switch 10, the MCU30 being electrically connected with foot-operated switch 20, with metal-oxide-semiconductor 40, the positive and negative rotating controller 50 of MCU30 electrical connection, there is the gear shifting device 60 of multiple speed stage, the motor 70 being electrically connected with metal-oxide-semiconductor 40, positive and negative rotating controller 50; Described MCU30 sends the pulse-width control signal with the dutycycle corresponding with speed stage according to the selected speed stage of gear shifting device 60 to metal-oxide-semiconductor 40, and described metal-oxide-semiconductor 40 is according to the rotating speed of the duty cycle adjustment motor 70 of pulse-width control signal.
When use, children can freely select speed stage by gear shifting device 60, MCU30 sends the pulse-width control signal with the dutycycle corresponding with speed stage according to speed stage to metal-oxide-semiconductor 40, by Duty ratio control metal-oxide-semiconductor 40, by the rotating speed of metal-oxide-semiconductor 40 governor motors 70, the final rotating speed of selecting motor 70 by switching different speed stages, realize the how fast selection function of battery-driven car, such as: gear shifting device 60 has at a high speed, middling speed, three speed stages of low speed, children select high gear, the dutycycle of the pulse-width control signal that MCU30 sends to metal-oxide-semiconductor 40 is 100%, now motor 70 at full throttle turns round, battery-driven car at full throttle travels, children select middling speed gear, the dutycycle of the pulse-width control signal that MCU30 sends to metal-oxide-semiconductor 40 is 70%, now motor 70 70% running at full throttle, battery-driven car 70% travelling at full throttle, children select low gear, the dutycycle of the pulse-width control signal that MCU30 sends to metal-oxide-semiconductor 40 is 40%, now motor 70 40% running at full throttle, battery-driven car 40% travelling at full throttle.Certainly, this is casehistory, and gear shifting device 60 is not limited to only have high speed, middling speed, three speed stages of low speed, and the corresponding dutycycle numerical value of speed stage is also not limited to the numerical value in example.
The utility model limits the dutycycle of the pulse-width control signal that MCU30 sends by the gear shifting device 60 that has multiple speed and select, by Duty ratio control metal-oxide-semiconductor 40, the dutycycle difference that different speed stages limits, thereby realize the adjusting to motor 70 rotating speeds, can provide multiple speed to select, there is how fast function, can meet various children's needs.
The above, it is only the utility model preferred embodiment, not technical scope of the present utility model is imposed any restrictions, therefore any trickle amendment, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
